Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

perf-theory-tester
Test hypotheses using controlled experiments.
Follow docs/perf-requirements.md as the canonical contract.
Required Steps
- Confirm baseline is clean.
- Apply a single change tied to the hypothesis.
- Run 2+ validation passes.
- Revert to baseline before the next experiment.
Output Format
hypothesis:
change:
delta:
verdict: accept|reject|inconclusive
evidence:
- command:
- files: Constraints
- One change per experiment.
- No parallel benchmarks.
- Record evidence for each run.
